HOG-TROUGH.

Specification of Letters Patent.

Patented Dec. 12, 1916.

Application filed May 17, 1915. Serial No. 28,703.

T 0 all whom it may concern:

Be it known that I, ANDREW A. FAIR, a citizen of the United States,residing near Pierson, (residence being in Cherokee county,) in thecounty of Woodbury and State of Iowa, have invented certain new anduseful Improvements in Hog-Troughs; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention relates broadly to improvements in stock feeding devices,and more particularly to hog troughs, the object of the invention beingto provide a simple, yet eflicient means of detachably securing devicesof this class in the runways of pens of the stock, whereby they may bereadily removed for cleaning or for other purposes, Without thenecessity of entering the pen or the like.

With this general object in view, the invention resides in certain novelfeatures of construction and in the unique combination of partshereinafter fully described and claimed.

In describing the invention, I shall refer to the accompanying drawingswherein like reference characters designate corresponding partsthroughout the several views and wherein;

Figure 1 is a front elevation of the invention; Fig. 2 is an end viewthereof; Fig. 3 is a vertical transverse section as seen on the planeindicated by the line 3-3 of Fig. 1; Fig. 4 is a similar view showingthe manner in which the trough proper is removed from the supportingframe thereof; Fig. 5 is a bottom plan view; Fig. 6 is a detaillongitudinal section as seen on the plane indicated by the line 66 ofFig. 2; and Fig. 7 is a top plan view, showing one manner of securingthe trough carrying frame to the upright wall of the pen.

In these drawings which constitute a part of the application, thenumerals 1 designate a pair of substantially rectangular upright endframes which have inlet throats at their front ends as disclosed moreparticularly in Figs. 1 and 4, said ends being of slightly greaterheight than the rear ends of the frames. The frames 1 are formed ofangle iron bars bent into U-shape formation, the free ends 8 of thesebars being disposed at the front of the frames and being connected byupright bars 4: riveted or otherwise rigidly secured to the outer sidesthereof. It is to be observed, that the laterally extending flanges ofthe two angle iron bars eX- tend toward each other and are disposed atthe outer edges of the numerous bars of the frames, with the exceptionof the bars a, the latter having no flanges in order that the front endsof the frames 1 may remain open for a reason yet to he described.

The two frames 1 above described are adapted to receive therein theopposite ends of the trough proper, in order to rigidly support thesame, it therefore becoming expedient to rigidly connect said frames.For this purpose, any number of longitudinally disposed bars 5 mayberiveted or otherwise secured at their opposite ends to the bottom barsof the frames 1, two bars 5 being shown in the present application ascrossed at their intermediate portions and connected at these points. Byso connecting the two end frames 1, a main frame structure is pro videdin which the trough 6 is removably housed.

The trough 6 is shown in the present embodiment of the invention asbeing of semicylindrical formation and as having its opposite endsprovided with rectangular end frames or members 7 which are received inthe frames 1 between the flanges thereof, removal of the trough beingnormally prevented by the upright stops 8 which are bent upwardly fromthe front ends of the lower bars of said frames 1, such stops being ofsuflicient height to abut the front ends of the frames or members 7 whenthe latter are confined therein, but being disengaged by said frameswhen the latter are raised the necessary amount, whereupon the entiretrough may be pulled forwardly and either totally or partially removed.

In applying the invention to use, the frame structure is secured by anypreferred means, either to the floor of the pen or the like or toupright cleats 9 which are secured to the inner side of the wall P ofsuch pen (see Fig. 7 In either case, the front ends of the frames aredisposed immediately in rear of an opening 0 formed in the afore saidwall, such opening being of sufficient size to allow the trough 6 to beremoved therethrough, this being essential since by raising said troughthe necessary amount to disengage the stops 8, it may be pulledforwardly, thus allowing the feed to be device will be highly eflicientand durable and will possess a number of advantageous features.

In the drawings, certain specific details of construction have beenshown for accomplishing probably the best results and in the foregoing,such details have been described, but it will be evident, I need not belimited thereto otherwise than to the extent to which the appendedclaims restrict me.

I claim n 1. In combination, a movable trough, a pair of rectangular endmembers secured one to each end thereof and having horizontal 'top andbottom edges, and upright front and rear edges, fixed L-iron bottomedges receiving' in their angles the bottom bars of the end members,stops rising from the front ends of the L-iron bottom bars in advance ofsaid end members, upright L-iron bars rising from the rear ends of saidL-iron bottom bars and receiving in their angles the upright rear edgesof the end members, L-iron top bars extending forwardly from saidupright L-iron bars and receiving in their angles the top edgesof saidend members, and additional upright bars connecting the front ends ofthe L-iron top and bottom bars and spacing said L-iron top bars abovethe end members a distance equal to the height of the aforesaid stops,said additional bars being spaced laterally from the front edges of saidend members to allow the latter andthe trough to be moved forwardly whenraised above the stops.

2. In combination, a hog trough having a pair of upright rectangularhorizontally elongated end members secured one to each end of saidtrough, a retaining structure for the trough consisting of a pair ofhorizontally elongated rigidly connected four-sided retaining framesreceiving the aforesaid end members, each of said retaining framesconsisting of an L-iron bar whose central portion stands upright andsnugly receives in its angle the upright rear end of the adjacent endmember, one end portion of said L- iron bar being bent laterally in ahorizontal direction and snugly receiving in its angle the bottom of theadjacent end member, the horizontal base flange of said horizontallybent end portion of the L-iron bar being bent upwardly to a slightextent in advance of the adjacent end member to form a stop to preventsaid end frame from being withdrawn from its respective retaining frameuntil raised above said stop, the other end portion of the aforesaidL-iron bar being bent in a substantially horizontal direction andreceiving in its angle the top of the adjacent end member, thelast-named horizontally bent portion of the L-iron bar being inclinedupwardly from its fixed to its free end to such an extent as to allowthe front end of the adjacent end member to be raised above itsrespective stop, and an upright bar secured to the outer sides of bothhorizontally bent portions of the L-iron bar at the free ends thereofand spaced laterally from the end members, said bars being adapted forcontact with upright cleats at the ends of a horizontally elongatedopening in the side of a pig pen and being formed with bolt holes toreceive bolts passed through 7 said cleats.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
